The Einhell TE-CI 18/1 Li is a cordless impact driver designed for tightening and loosening screws. Before using the tool, ensure the battery is fully charged using the provided charger. Always check walls for concealed electrical, gas, or water lines before screwing into them. When not in use, set the rotation switch to the center position to lock the trigger.
Device description
The tool features a 1/4 inch bit mount, a battery capacity indicator, a rotation direction switch, an on/off trigger, an LED light for illuminating the work area, and a removable belt clip.
Operation
Charging the battery
Remove the battery pack from the handle by pressing the pushlock button. Check that your mains voltage matches the rating on the charger. Insert the charger plug into the socket; the green LED will flash. Slide the battery onto the charger. Refer to the charger indicator table for status details.
Bit change
To insert a bit, pull the sleeve on the bit mount forward, insert the bit until it stops, and release the sleeve. Ensure the bit is securely seated. To remove, pull the sleeve forward and pull the bit out.
Rotation and speed
Use the slide switch above the trigger to set the rotation direction (clockwise/counter-clockwise) or to lock the trigger. The trigger allows for infinitely variable speed control; the further you press it, the higher the speed.
Cleaning and maintenance
Keep safety devices, air vents, and the motor housing free of dust and dirt. Wipe the tool with a clean cloth or blow it with low-pressure compressed air.
